QED Reference X-Tube 400 Speaker Cable

QED's flagship speaker cable, the award winning Genesis Silver Spiral Bi-Wire cable is the result of over 40 years of scientific research and development into speaker cables.

Cable sold per metre - unterminated.


QED''s multi-award winning X-Tube 400 speaker cable, utilising X-TubeTM technology

Silver plated oxygen free copper tubular conductor geometry. For use in the finest hi-fi and home theatre systems.this design delivers a massive cross-sectional area using X-Tube technology to eliminate the skin effect whilst maintaining a user friendly figure of 8 geometry. This is QEDs ultimate affordable upgrade for high end systems.

X-Tube Technology
At low frequencies both X-TubeTM and conventional stranded/solid core speaker cable convey signals in a linear way. However, at higher frequencies, X-tubeTMretains a near-linear signal transfer, whereas the conventional stranded/solid core cable fails to conduct higher frequencies uniformly across the entire conductor area. The result is greater detail which would other wise be lost in ordinary cables.

Silver plated 99.999% oxygen free copper conductors

Provides a low frequency path for the audio signal and delivers stunning high frequency detail
